GEORGE E. SAVAGE AND JAMES W. CHAPMAN, OF MERIDEN, CONNECTICUT,ASSIGNORS TO MANNING, BOWMAN & COMPANY, OF MERIDEN, CONNECTICUT, ACORPORATION OF CON- NECTICUT.

To all whom it may concern:

Be it known that we, GEORGE E. SAVAGE and JAMEs W. CHAPMAN, bothcitizens of the United States, residing at Meriden, New Haven county,Connecticut, have invented certain new and useful Im rovements inVapor-Stoves, of which the fol owing is a full, clear, and exactdescription.

This invention relates to vapor stoves of that class in which liquidfuel is vaporized and mixed with air before burning.

The objects of this invention are to construct a device of thischaracter in which the parts are of sim le construction and are readilyassemble or taken apart, and in which there is suflicient circulation ofair to secure the roper mixture in the mixing chamber, and to preventthe other parts from becoming overheated.

In the drawings Figure 1 is a side elevation of one form of ourinvention. Fig. 2 is a top plan view of the same. Fig. 3 is an enlargedlan view partly in section of the burner. ig. 4 is a side elevation ofthe same partly in section. Fig. 5 is a transverse sectional view takenthrough the burner. Figs. 6, 7 and 8 are enlarged detail views showingthe rear connection between the plate ring and base. 'Figs. 9, 10 and 11are enlarged detail views showing the front connections between thesame.

In the construction illustrated in the drawings, 1 re resents a fontadapted to contain liquid fue 2 is a plate-ring.

3 is a bracket secured to the plate-ring, which supports the font.

4 is a base provided with legs 5-5-5.

6 is a flange depending from the outer edge of the plate-ring 2 and isadapted to engage the top of the base 4.

7 is alarge central aperture in the plate-ring above the burner.

8-8 represents a series of plate supports, and 9 is series of heatradiating apertures.

10 is a vapor burner provided with a series of gas vents 11. 12 is avaporizing chamber passing therethrough. 13 is a series of wires 1n saidchamber 12.

14 is a pipe leading from the font 1 to the chamber 12.

15 is a needle valve of the usual construction to regulate the opening16 in the chamber 12, and operated by the usual handle.

Specification of Letters Patent.

Application filed April 29, 1907.

Patented Feb. 23, 1909.

Serial No. 370,952.

17 is a bracket secured to the end of chamber 12 and supporting the 0 enend 19 of the mixing chamber 18, the ot or end of which is supported bythe depending inclosed central chamber 21 of the burner 10.

22 is a vapor discharge tube connected to the vaporizing chamber 12through the passage 16 and has the discharge opening 23 opposite the end19 of the mixing chamber 18.

24 is the side member of the base 4 and is provided with a series ofventilating openings 25.

26 is the bottom member of the base 4.

27 is a pan formed in or made se arate from and secured to the bottommem er 26 under the burner 10.

28 is a series of large vent openings in the bottom member. The edges ofthe bottom 26 around these openings 28 have up-turned flanges 29 toprevent any overflow of the liquid fuel should same escape from pan 27.

The depending flange 6 of the plate-ring 2 and the side member 24 areprovided with corresponding cut-away parts 30-3O to receive the pipe 14at .the rear and the externally screw-threaded sleeve 31 of the needlevalve 15 in front.

32-82 are locking members extending inward from the flange 6 at the rearadapted to engage in the openings 3333 in the member 24 on each side ofthe openings 30.

34 is a washer mounted on the externally screw-threaded sleeve 31 0f theneedle valve 15 and is provided on each side with a looking member 35adapted to enter through the corresponding openings 3637 in the flange 6and the member 24.

38 is a nut to secure the locking washer in place.

39 is a nut securing the pipe 14 to the bracket and 40 is a heatinsulating washer at this point.

The operation is as follows: The font is filled with liquid fuel, theneedle valve opened, and as the stopper in the font is perforated theliquid passes down through the pipe 14 through the chamber 12 andaperture 16 into the discharge tube 22 and through the dischargeaperture into the pan 27. The flow is then shut off and the liquid inthe pan ignited through one of the apertures 41 provided for thispurpose in the side member 24, or elsewhere. As soon as the heat in thevaporizing chamber becomes sufficient to vaporize the liquid, the needlevalve is opened and properly regulated and the vapor passes therethroughinto the mixing chamber 18, where it mixes with the air, and thencethrough the gas vents 11 in the vapor burner 10. If the vapor does notignite from the flame in the pan, combustion may be started by applyinga match.

One of the advantages of this construction is the simplicity and ease ofassembling the parts. The needle valve, burner, vaporizing chamber andmixing chamber are readily secured to the tube 14. The bracket 3 is madefast to the plate-ring 2. The tube 14 is secured in place in the bracket3 by the nut 39, while the other end of the sleeve 31 of the needlevalve lies within the recess 30 and the flange 6. The font 1 is securedto the end of the tube, and the washer 40, of asbestos or other heatinsulating material, is inserted therebetween. The plate ring with saidparts attached is placed upon the side member 24 of the base with theprojections 32 engaging the recesses 33 at the rear thereof, and theopenings 36 and 37 coinciding at the front thereof. It is only necessarynow to move the locking washer 34 into engagement with said openings andsecure the same by the nut 38 to complete the apparatus, which will thenbe ready for use. The free space between the bracket 3 and the tube 14allows complete circulation of air about said tube, and together withthe heat insulating washer 40, tends to prevent the heating of theliquid in the font. The openings in the side and bottom of the baseallow a free circulation of air for the mixing chamber and insure a goodmixture therein, while the openings in the plate-ring secure theradiation of heat in the proper direction. As the plate supports 8 areflat on top, any sized receptacle may be placed over the burner.

This device is especially adapted for the use ofalcohol of either thecommercial or denaturized form, however we do not limit ourselves tothis form of liquid fuel, nor do we limit ourselves to the constructionherein shown as minor changes may be effected without departing from thescope of this invention.

What we claim is 1. In a two-part vapor stove, a plate ring, a font, avapor burner and vapor generating parts therefor carried by said platering, a separable base and locking connections arranged to secure saidseparable members to each other and to secure said vapor generatingparts to said members.

2. In a two-part vapor stove, a plate-ring, a font, a vapor burner andva or generating parts therefor carried by sai plate-ring, a separablebase having a perforated bottom, and a pan in said bottom under saidvapor generating parts, and means for connecting said plate-ring andbase, comprising engaging members on opposite sides thereof.

3. In a two-part vapor stove, a plate-ring, a font, a vapor burner andvapor generating parts therefor, including a projecting sleeve,

all mounted upon said plate-ring, a separablebase, a plurality oflocking members to secure the separable members, some of which arecarried on opposite sides thereof, and an engaging Washer mounted uponsaid projecting sleeve, adapted to engage both of said members, andmeans to secure said washer in position.

4. In a twopart vapor stove, a plate-ring, a font, a vapor burner andvapor generating parts therefor mounted on said plate-ring, a separablebase comprising side and bottom members, engaging means for saidplate-ring and side member, a pan in said bottom member under said vaporgenerating parts, said bottom member having a plurality of vent openingswith up-turned edges to prevent overflow from said pan.

5. In a two-part vapor stove, a plate-ring, having an exterior flange, avapor burner, a vaporizing chamber passing therethrough, a fontconnected to one end thereof by a pipe and supported upon saidplate-ring, a mixing chamber in communication with said burner andvaporizing chamber, a regulating valve between said chambers having asleeve passing through said flange, a base having a side member adaptedto be engaged by said flange and provided with recesses to receive saidpipe and sleeve, said flange and side member provided with interlockingmeans on opposite parts thereof, locking means carried by said sleeve toengage both said flange and side member, and means on said sleeve tosecure said locking means in place.
